The National Aboriginal and Torres Strait Islander Immunisation Network was established by NCIRS in 2006 to coordinate support for those involved in providing immunisation services to Aboriginal and Torres Strait Islander people nationally. The Network is administered by the National Indigenous Immunisation Coordinator from NCIRS.

The role of NATSIIN is to:

provide advice to the National Immunisation Committee (NIC) on matters related to the immunisation of Aboriginal and Torres Strait Islander people nationally

promote communication and coordination between the NIC, service providers to Indigenous people and immunisation program managers
